Exit present-day food shortages are blamed on all of the following except
a. high prices for seeds, fertilizers, and irrigation, which has limited the productivity of farmers in poor countries.
b. poorer countries that do not have the infrastructure in place to maintain food resources, meaning that raw materials often rot before they are consumed.
c. climate changes brought on by global warming, which have contributed to a reduction in food production.
d. the growing global population, which has put an extra strain on the available resources.

b. poorer countries that do not have the infrastructure in place to maintain food resources, meaning that raw materials often rot before they are consumed.
